Application filed March 11,

Be it known that I, ALBERT L. GALUBHA, of Dorchester, in the county of Suffolk and tain new and useful Improvements in Power Plants; and I do hereby declare the.- following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

' This invention relates to improvements in the supply of fuel to an internal combustion engine.

- One object of the invention is to provide means whereby the engine may be readily.

'.A further object is to provide means internal combustion engine can producer gas or liquid the other withbe run with either fuel or changed from one to A further object is to so construct and arrange the a paratus that draft may be furnished to raw up a gas producer fire and. result in the making of good gas without the necessity for the use of a fan or exhauster or other such means.

A further object is to increase the power of an engine to be operated with roducer gas, by enabling the engineer to enrich weak producer gas explosive mixture with more owerful mixture made from liquid fuel.

A further object is to rovide means which will enable absolute an instantaneous control of the explosive mixture so that the engine may be supplied with producer as alone; with the most powerful mixture that can be made with liquid fuel alone, or with explosive mixtures of producer gas and liquid fuel giving power intermediate of those of producer gas alone and li uid fuel alone.

A further object is to provi e means which will enable a change from one ratio of gas mixture to liquid mixture to another ratio at any time.

A further object is to provide means which willprevent the valve which supplies liquid fuel frombeing 0 ened beyond a certain limit and thus enab e the use of hi h engine compression for producer gas an yet not get as high or too high compression for liquid fuel mixture;

A further object is to start a producer gas internal combustion engine easily, by

start from lltglld fueland air, than from producer as an air. I

A rther ob'ect is to provide means whereby the exp osions can be made to contmue and the engine kept running, although the mlxture of air and producer gas may not be in ro er condition to explode.

A rt er ob'ect is to completely control the ower whic the engine will give from no oad to all the engine will carry, with the use of one valve, regardless of whether producer as or liquid fuel is being used.

Wlth t ese objects in view the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims. In the accompanying drawings Figure 1 s a-vrew of a plant with some of the parts in se ct1on,showmg the application of my invention, and Figs. 2, 3, 4 and 5 are views showing different valve positions.

1 re resents an internal combustion englne w ioh 1n the present instance is shown as a three cylinder engine although my improvements are adaptable for use on other types of internal combustion en ines.

2 represents a gas producer 0 any referred construction and 3 a gas scru her with which the outlet of the gas producer communicates through the medium of a pi e 4. A pipe or stack 5 communicates with tiie pipe 4 and at the intersection of these pipes, a three-way valve 6 is located and adapted to control the passage of gas from the producer to the scrubber or permit it toescape through the pipe or stack 5. c

A pipe 7 communicates with the scrubber for conveying producer gas to the engine. This pipe is provided with a valve 8 and at a point in advance of this valve, the pi e 7 is connected by means of a pi e 9 with t e inlet ports of the engine cyhn ers. At the intersection of the pi es 8 and 9 a threeway valve 10 is located and from this valve the pipe 7 is continued and communicates with a carbureter or vaporizer. Between the valve 10 and the carbureter or vaporizer 11, a valve 12 is located. A stop for the handle 14 of the valve 12 to revent the latter from bein opened beyon a predetermined extent, or reasons which will hereinafter appear. A pipe 15 communi cates with-the pipe 7 between the valves 8 and 10 for the purpose of conveying air providing at once an explosive mixture which can usually be made more easily at the 13 is providedstarted with liquid fuel to positions of the valves 8 and liquid fu located in the pipe 15.

To start the engine, thevalve-lO will be placed in the position air to the en me and open the passage for thesupply 0 liquid fuel alone. Thus the engine W111 be started in a manner slmilar to that employed with asolene and other liquid fuel engines. T e engine may be the exclusion of producer gas and air with the valve 10 disposed as shown in Fig. 4 and the valves 8 and 17 closed.

For the purpose of drawin up the producer fire to improve the qua ity of the I producer gas, (the enginebein kept running by liquid fuel), the valve 6 Wlll be moved to the position-shown inFig. 1 and the valve 10 to the osition shown in Fig. 4; The valves 8 and 17' (first the valve 8 and a little later the valve 17) will be gradually o ened a little at a time. At first, smoke and poor gas simply dilutes liquid fuel charges going into the engine but as the producer gasimproves, it, with air, willburn when air valve 17 is adjusted to supply a proper pro ortion of air to the mixing chamber 16. s soon as the quality of gas will permit thevalve 8 to be set in running position and valve 17 in position to give proper mixture of air, the operator will begin slowly to close the throttle valve 12 and when the latter is practically closed the liquid fuel supply to the carburetor may be shut off. By leaving the valve 12 open a very little for a few minutes, the carburetor will be dried out and then the valve 12 may be closed completely, The op ,erator will now suddenly throw the valve 10 to the position shown in Fig. 1 and test position of valve 17 by slight changes until a mixture giving best results is obtalned. The liquid fuel supply being now out off and the valves 8 and 17 open, the engine will be running with producer will be disposed approxlmately in the positions shown in Fig; 1, assuming that the producer is of straight suction type. With gas pressure above atmospheric pressure, the and 17 will be exchanged.

Should it be desired ful explosive than can ducer gas and air, producer gas and air fall in quality, more or less liquid fuel may be mixed therewith and such result may be attained by manipulation of the valve 10 :Fpr instance said valve 10 may be disposed in the position shown in Fig. 5 when producer gas mixed with air to use a more powercylinder. It has been hereinbefore stated shown in Fig. 3. This I will close the passage of producer gas and; v com ression with gasolene alone,

ression is liable to pre-ignite gas and the valves be provided by pro-' or should the mixture of will enter the pipe' 9, be 'in- 'termixed therein and supplied to the engine that the stop 13 is to prevent the valve 12 from bein .cpened too far. The reason for this is as follows: It isdesirable to use perhaps 150 pounds per square inch compression'in the "engine cylinder for producer gas but it is not safe to use over about 80 ounds the eat of com the gasolene. en the engine 1s madeto ive the right compression for producer gas &e partial closing of the valve 12 when runecause.

nin on liquid fuel reduces the amount of exp o'sive mixture going to the engine and consequently the compression pressure or tem erature maximum to a degree suitable for iquid fuel. Having fully claim as new and desire to secure by LettersPatent, is,-
